There are two ways to use oxygen equipment at altitude -- a right and wrong. Don't be a fish out of water when you fly above 18,000 feet. Learn how to use oxygen the right way NOW - then you won't have to re-learn the hard way after an unpleasant experience or two.

A few points on reviving a fellow crew member who has passed out due to oxygen lack--an opportunity that may well be yours some day!

  1. KEEP CALM -- Just because a man passes out from oxygen lack is no sign that he's at death's door. TAKE YOUR TIME. Remember you're going to need OXYGEN yourself for the job at hand. If you don't heed this, there'll be TWO to revive instead of only one.
  2. PLAN how you're going to revive the victim--then proceed with the least possible exertion to yourself.
  3. DON'T attempt to drag or carry the victim to a supply of oxygen. If he's not near a regulator hose, take portable oxygen TO him. Take plenty -- 3 or 5 bottles -- some for him, plenty for you. If he's near a regulator hose you're in luck. Connect his mask and NOW use the "Emergency." Ordinarily you'll almost blow him right back onto his feet.
  4. GET ASSISTANCE. Have someone keep an eye on you, and supply you with refilled walk-around bottles if needed.
  5. Connect the victim to a walk-around bottle. Ordinarily he'll come to in a matter of seconds. But watch him. He'll be punch drunk and confused as to what's going on.
  6. After he's emptied one bottle, give him another. Then put him on a third and assist him ON HIS OWN POWER to a regulator. Turn the Auto-Mix "OFF" and let him breathe pure oxygen for 5 or 10 minutes. Ordinarily he'll be able to return to his regular duties.
  7. If the victim has been out for a number of minutes he may present more of a problem. Breathing becomes shallow -- and the demand system gives just what is asked of it -- a weak inspiration brings a small squirt of oxygen. So, you'll have to help him with artificial respiration, learn it -- your flight surgeon will show you how.

Caution: Above 20,000 feet, get assistance to give artificial respiration. It will be strenuous work -- a job for several men, not one. Take turns of one to three minutes each.

THE B-29 AT HIGH ALTITUDE

The B-29 is designed to permit you to fly at high altitude without the usual disadvantages of extreme cold, diminished pressure, and decreased oxygen. This is done by the use of pressurized, heated compartments. A highly efficient oxygen system is also incorporated in the ship for use when the cabins are unpressurized.
